Influence of an acute administration of magnoflorine (MAG) on the memory impairment induced by an acute injection of scopolamine (SCOP), expressed as latency index (LI) during the short-term (a) or long-term (b) memory acquisition using the PA test in mice. A non-effective dose of MAG (10 mg/kg), effective dose of MAG (20 mg/kg) or vehicle were administered 15 min before vehicle or SCOP (1 mg/kg) injection. All drugs were administered 15 min before the first trial and animals were re-tested 2 h (for short-term memory) or 24 h (for long-term memory) later; n = 8–11; the means ± SEM; * p < 0.05; *** p < 0.001 vs. VEH/VEH-treated group; ^ p < 0.05 vs. VEH/SCOP (1 mg/kg)-treated group; Tukey’s test.
